采用二维数值计算方法，研究了在重力场和非重力场作用下，具有热场和垂直磁场梯度的立式圆柱形容器中磁场对顺磁和反磁流体的影响。在重力场和非重力场中，均可利用磁场梯度产生的磁化力来控制顺磁和反磁流体的换热速率。这些现象可以通过将磁化力场可视化来成功地解释。
Two-dimensional numerical computations were carried out in order to clarify the effect of magnetic field on paramagnetic and diamagnetic fluids in a vertical cylindrical container with thermal and vertical magnetic field gradients under both gravitational and nongravitational fields. In both gravitational and nongravitational fields, the magnetizing force that was produced by the gradient of magnetic field could be utilized to control the heat transfer rate for paramagnetic and diamagnetic fluids. These phenomena could be successfully explained by visualizing the field of magnetizing force.
